PAPER CLAMP OR GUIDE FOR FRONT-STRIKE TYPEWRITING MACHINES.

Specification of Letters Patent.

Patented June 4.. 1907.

Application filed March 16,1907- Serial No. 362,782.

To all whom it may concern:

l Be it known that LWiLLiAM R. Fox, a

.paper clamps or guides for frontestrike typecitizen of the United States, residing at Grand Rapids, in the county of Kent, State of Michigan, have invented certain new and useful Improvements in Paper Clamps or Guides for Front-Strike Type-Writing, Machines,.. of which the following is a specification.

Thisinvention relates todanprovements in I freouently desirable to increase the pressure,

and I have provided an improved means and devices for accomplishing this result, both as to the method of increasing the tension and the arrangement of the parts.

The objects of my invention are accom plished by the devices and means described in the following specification.

The invention is clearly defined and poin ed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this speciiication, in which:

Figure 1 is a detail plan view of my improved typewriter paper clamp and guide, in place; Fig. Zisa detail sectional view on the irregular section; line 2- 201 Fig. 1, and in the line correspondingto line 22 of Figs. 5

and i, showing details of construction; Fig-e3 is an inverted plan view of the front port'reii of my improved paper guide and clamp; and Fig. l is a front elevation of the device; !the platen is only mdica ted in Fig. 2. In the drawings, similar numerals of reference refer to similar parts throughout the several views. 7

Referring to the numbered parts of the drawin a small portion only of the typewriter arne l is here illustrated, it being a cross-bar or portion of the top of the'irame. To this is secured the adjustable arm Z'by means of screws 11 in slotted holes there through Ears 8-8 are turned up at each. side of the front end of this arm or plateZ, and between the same is pivoted the upwardly extending paper guide 3, made of thin elastic metal as steel, which is slotted at its upper edge at 4, which slot is opposite the printing point of the platen and just beneath the said printing point or one o'r'rnore spaces removed; The slot 4 is a definite number of scale spaces wide, preferably two. The ends of this are outturned to permit the free passage of the platen 12, with the paper thereon, and so as to pass the usual paper fingers that rest on'the platen. The corners at each side of the slot are slightly beveled so that they will-not catch the paper fingers in assing by and also to insure free passage oi the-paper and platen. A. finger 5 extends rearwardly from the bottom of this pivoted clamp '3' through an aperture in the front end of the said plate 2 and downwardly and rearwardly,

the lower end of the same being turned parallel *ith the plate 2.

A spring. 6 is on the top of the plate 2 and is secured thereto by a suitable rivet 7 and its forward free end rests upon the upper side of the arm 5, holding it normally downward and thereby holding the paper clamp yieldingly in contact with the platen by a gentle pressure, which is sufficient for" ordinary purposes; When, however, it is desired to print upon a stifi card, or, for any reason, it is necessary or desirable to exert considerable pressure on the paper against the platen, I provide beneath the plate 2 a swinging arm 9 on pivot 10, the front side of which is beveled to strike over the upper side of thearm 5 and force the same down by a wedging action, thereby forcing the paper clamp or guide J 3 against the paper very securely and, with suificient force to cause any card or stifltpaper to be clamped properly against the platen at this point. The paper guide or clamp 3 is sufficiently elastic to accominodate'the thick card or paper and allow it to pass and at the same time is sufficiently strong to force the same against the platen. lever is very accessible to the operator; it only needs to be drawn forward to secure this extra clamping effect, and can be immediatel The end o'li this I pushed back and release the same when the occasion for extra pressure is passed.

Having thus described my invention, what I. claim as new and desire to secure by Letters 5 Patent is:

1. The combination with a typewriter frame, of a forwardly extending plate 2 adjustably secured to the said typewriter frame, the same containing a suitable aperture at 1 the front and provided with ears 88 at each side a'paper clamp 3 pivoted to the ears 88 and suitably slotted opposite the printing point and having a finger 5 extending through the slot in the plate and beneath the same; a

I 5 spring 6 on the upper side of the plate 2 and contacting with the upper side of the finger 5 to hold the paper clamp yieldingly in position; and an arm 9 pivoted at to the under side of the plate 2 and beveled to strike above '2 the finger 5"and force the clamp or paper guide 'firmly into position, co-acting for the purpose specified.

2. The combination with a typewriter frame, of a forwardly extending plate 2 ad- 5 justably secured to the said typewriter frame, the same containing a suitable aperture at the front and provided with ears 8+8 at each side; a paper clamp 3 pivoted to the ears 88. I a finger 5 extending through the- 3 slot in the plate and beneath the same; a

having spring 6 on the upper side of the plate 2 and contacting with the upper side of the finger 5 to hold the paper clamp yieldingly in posi tion; and an arm 9 pivoted at 10 to the under side of the plate 2 and beveled to strike above the finger 5 and force the clamp or paper guide firmly into position, co-a'cting for the purpose specified.

3. The combination with a typewriter 4 frame, of a forwardly extending plate 2 secured to the said typewriter frame, provided with ears 88 at each side; a paper clamp 3 pivoted to the ears 8-8, having a finger 5; a blade spring 6 on the upper side of the plate 2 and contacting with the upper side of the finger 5 to hold the paper clamp yieldingly in position, for the purpose specified.

4. The combination with a typewriter frame,- of a forwardly extending plate 2 se- 5 cured to the said typewriter frame, provided with ears 88 at each side; a paper clamp 3 pivoted to the ears 8-8, having a finger 5; a spring 6 on the upper side of the plate 2 and contacting with the upper side of the finger 5 5 to hold the paper clamp yieldingly in position; and adjustable means for securing the finger 5 in a fixed relation to the plate 2, for the purpose specified.
